CANVAS-CEMENTEE.

To all whom it 'mc/y concern:

Be it known that l, THOMAS G. PLANT, a citizen of the 'United Statesj residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Canvas-Cementers, of which the following description, in connection with the accompanying drawings, is a` specification, .like numerals on the drawings representing like parts.'

The invention to be hereinafter described relates to canvas cementers and more particularly to those devices for applying cement or other adhesive material to a strip of fabric, such as canvas or the like, which is to be applied as areinforce to the insotes ofA boots and shoes. h

The aims and purposes of the invention are to provide a simple device of this character which will effectively applyr cement or other adhesive material to one surface of the canvas or fabric to be treated.

rlhe characteristics of the invention will best be. understood from the following description and accompanying drawings of one form or embodiment thereof, it being understood that the invention in its true scope is clearly defined by the claims.

In the drawings, Figure l is a top or plan view of n apparatus embodying the present invention; Fig. 2 is a side elevation thereof; Fig. 3 is a section on line SH3 of Fig. l; and Fig. t is a section on line 4 of Fig. l.

Having reference more particularly to Figs. l and 2, l isa tank or other suitable receptacle for containing the cement or other adhesive in liquid form and is preferably provided with support-ing feet 9. by which it may be sustained on a proper bench or table, if desired. `The upper surface of the tank is provided with an opening S, Figs. l. and 2, preferably closed by a swinging cover 4 pivotally mounted at 5 on the top of the tank and provided with a handle or lug (3 by which it may be swung to one side for the purpose of uncovering the opening 3 for the supply of the adhesive or cement. An overhanging lip 7 may be provided for engaging the free end of the cover or plate 4.

ounted on suitable bearings 8 preferably sustained by the sides of the tank .'t. is a shaft 9 carrying a large plane surface roller 10, said roller j ireforably dipping down into thecen'ient or other adhesive material, the height of which in the tank 'l is shown by the dotted line ll, Fig. 2. This roller l() Specification of Letters Patent.

constitutes one convenient form of support- Ving` surface for the fabric upon which the fabric is pressed by its pulling or drawing action as it passes about said surface, so that the liquid. cement does not penetrate the fabric and get to the said surface, it being noted that said surface, whether movable or fixed, has closely contacting therewith, throughout the entire extent of said surface beneath the cement, the closely drawn fabric. ln other words the supporting surface where it dips into the cement is covered and protected by the fabric, one surface of which is to be coated. For convenience of identification the said surface may be termed a supporting clement for the fabric extending into the liquid in the tank.

The large roller lO is preferably of sufficient length in an axial direction to provide for the application of cement; or other adhesive to the two strips of fabric or canvas 1Q, 13 simultancously or otherwise.

illounted upon suitable projecting lugs ld on the top of the tank is a shaft l5 carrying rollers 1G about which the fabric l? passes from a source of supply in the direction of the arrow toward the roller l0. y

lilounted on the opposite side. of the roller l0 are the rolls 18 substantially the same as the rolls 1G, said rolls t8 being sustained by a shaft l5) supported by lugs i2() projecting upwardly from the top of the tank l. The lugs 2() are preferably son'iewhat longer than the lugs or bearing supports lll so as to accommodate beneath the rollers 18 the Scrapers 2l.

The preferred 'torni of the scraper is best shown in liig. 3, wherein it is formed of a plate having a beveled end 2Q and slots 23 through which pass the guiding screws 24 which are screw threaded in the top of the tank l, the construction being such that the scraper is free to move back and forth on thc guide screws 2l. The rear portion of the scraper is provided with an upturned flange against which bears the end of a plun- Igerr 2G movable longitudinally in a slot 27 formed in a bearing 28 projecting from the top of the tank. Screw threaded into the rear part of the projection QS-is an adjusting screw 29 between the end of which and the plunger 26 is a spring 30 which acts normally to force the plunger 26 forward or to the left, Fig. 3, and the scraper 2l toward the. roll l0 and well under the guiding rolls 18, the construction being such that as the lio fabric passes in the direction of the arrow, Fig. 2, about the roll 16 and the roll 10-in the tank 1 and emerges from the tank over the edgey of the scraper 21and about the rear of the roll 18, the scraper 21 will remove from the face of the fabric all surplus cement or other adhesive which Will run back into the tank. y

It will be noted that the rolls 16 and 18 are separated by a distance less than the di- ,ameter of the roll 10, the eii'ect of Whiclris :that the fabric 17 in passing around the roll eXit portion of the fabric at 31.

bearing 32, Figs. 1 and 2, having a slot 33 for a rod 34 which supports a plow or wiper 35, said plow or wiper 35 beingconnected tol the rod 34 by means of a screw or other supy porting means 36, the construction being such that the plow or wiper 35 'may be forced against, the smooth surface of the roll 10 with suilicient energy to wipe therefrom any cement or ladhesive that may find its way to the surface of the roll 10.

The plow 35 is preferably formed as indicated in 1 and t, the bearing surface next the roll l0 being. curved in conformity with the curvature of the roll 10 and the side portions 37 being iiar'ed outwardly so that any adhesive or cement coming to the wiper Aor plow 35 will iirst meet the front portion 3S of the plow and, the roll l0 revolves, be wiped or plowed toward the edge or. central portion ofthe roll 10, as indicated in Fig. 1, whereby the surface ofthe roll 10 is kept substantially clean and free from adhesive.

By reference to Fig. 4 it will be noted that the sides of the wing portions 37 rise in a curve 39 from the surface of the roll 10 so Y that they are effeetually removed of cement '3Q have screw-fitted thereinto the adjusting screws 40, Figs. 1 and 2, the construction being such that upon proper manipulation of these adjusting devices the rod 3e, and consequently the plow carried thereby, may be forced into 'close contact with the roll 10.

What is claimed is:

l. In a device for applying an adhesive to one surface of a strip of canvas for application as a reinforce for insoles of boots and shoes, the combination of a tank for containing a liquid adhesive, a supporting element for the fabric extending into the element to cause the fabric to cling or press closely against the entire submerged surface of said element, and a scraper 2l bearing on the canvas directly after it leaves the said element and between it and said last named guide.

2. In a device for ap lying adhesive to one surface of a fabric fldr application as a reinforce for the insoles of boots and shoes,

. the combination of a tank containing liquid Rising from each side of the tank is a.

adhesive, a roll rotatably sustained therein and dipping into said adhesive, guiding ymeans disposed close to and above the said roll and separated a distance apart less than the diameter of said roll so that the fabric passing about said guiding means and the roll in the tank may cling close to the surface of the latter roll and have cement or adhesive applied to only one surface thereof,

the diameter of said roll so that the fabricv passing about said guiding means and the lroll in the tank may cling close to the surface of the latter roll and have cement or adhesive applied to only one surface thereof, a plow havingv side wing portions and disposed between the guiding means and bearing upon the upper part of the roll dipping into the tank, and means for forcing the plow onto the surface of said roll.

4. ln a device forapplying adhesive to one surface of a fabric for application as a reinforce for the insoles of boots and shoes, the combination of a tank containing liquid adhesive, a roll rotatably sustained therein and dipping into said adhesive, guiding means disposed close to and above the said roll and separated a distance apart less than the diameter of said roll so that the fabric 'passing about said guiding means andthe a plow having (":iveigino' side Wing port-ions provided with npwaroly curved plowing surfaces, and means for forcing ihe plow onto the exposefisinfaee of the roll in the tank.
